EDGE TRIMMER AND BURNISHER.

SPECIFICATION formingpart Of Letters Patent N0. 229,698, dated July 6, 1880.

Application filed February 21, 1880.

To all whom it may concern:

Be it known that I, DANIEL F. HALLAHAN,

I of Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented a new and Improved Edge Trinnner and Burnisher, of which the following is a specifica tion.

Figure 1 is a front elevation of the device. Fig. 2 is afront elevation of the same with the inner guide removed. Fig. 3 is a sectional elevation on line mm, Fig. 2. Fig. 4 is a transverse sectional elevation of the outer spider. Fig. 5 is a side elevation of a burnisher. Fig. 6 is a front elevation of a cutter.

Similar letters of reference indicate corresponding parts.

The object of this invention is to provide a device for trimming and burnishing the edges of soles of boots and shoes.

The invention consists of two spiders of equal diameters and having an equal number of arms that are fixed upon a shank or shaft between two circular disks or guides, which guides are of slightly greater diameters than the spiders, together with the cutters or burnishers that the said spiders carry on the ends of their arms; and it further consists of tangential cutters or burnishers (the cutters and bnrnishers being interch an geable) adj ustably fixed upon the ends of the spider-arms by means of screws that pass through slots in said arms, the spiders being so arranged that the cutters or burnishers on the one fit into or opposite the interspaces between the cutters or burnishers upon the other, and so that while one of the spiders remains fixed the other may be approached or withdrawn from it, whereby the device may be adjusted and applied to soles of any thickness.

In the drawings, A represents a shaft or shank provided with a collar, a, and with a screw-thread, 1), extending for a portion of its length.

The spider B, provided with arms I) 1), slotted near their outer ends, cut away, as at t, for the escape of fragments of leather that may be removed from the sole, and having a hub, f, projecting from one face, is held so that it cannot revolve on the shank or shaft A, between the collar a and the screw portion b of the said shank, and so that it will remain in position when the opposite spider is moved from it by a key or spline, g; and upon this hub f is loosely fixed the outer guide, (3, so that it may revolve, and said guide 0 is provided with perforations h for the escape of fragments of leather that may be removed by the cutter from the sole of the boot or shoe. A coiled spring, D, placed about the shank A, between the collar a and the outer guide, (J, serves to hold the said outer guide, 0, closely against the spider B and against the outer edge of the shoe or boot sole M when the device is in operation, and permits the guide 0 to adjust itself to the irregularities of the sole.

The spider E, which is designed to be a duplicate of spider B, is screwed on the shank A and adjusted so that its arms 70 shall come opposite the interspaces between the arms I) b of the said spider B. On the hub of this spider E the inner guide, F, is loosely titted, so that it may readily revolve, and is held in place, but so that it can be screwed closer to or farther from said spider B, by the screw-collar or nut G, said guide F also being provided with openings 2: for the escape of the chips of leather removed from the sole.

Secured on the ends of all the spider-arms b b 70 k with screws m m, that enter the slots n n of said arms, as shown, are the cutters H H, that are radially adjustable by means of said screws and slots, so that the cutting-edge 0 of each cutter may be made to extend to any desired degree above the back of the cutter before it.

The series of cutters E[ on the spider B have their flanges on the opposite side to those of cutters H on the spider E, thus causing the flanges of the several cutters to alternate from side to side around the periphery of the trimmer and burnisher, thereby trimming both the upper and lower edges of the boot or shoe sole alike.

The rim 1? of the outer guide, 0, is designed to project over the cutters H far enough to cover the first or outer beveled edge thereof.

The device, when used, is revolved by suitable means, and the boot or shoe on a last is held so that the edge of its sole M is then grasped so firmly between the guides G F that the said sole-edge shall not be pressed down and out of shape by the pressure of the cutters or burnisbers. The outer guide, U, presses against the outer edge of the sole M and revolves with the device, and the inner guide, I", simply turns independently, as the shoe or boot is moved, in the groove between the upper and the sole of the bent or shoe. The cutters 11 II have beveled edges and simulders, as shown at q 1', respectively, that form the desired channels and ribs on the edges of the sole M as they revolve and trim said sole.

The inner cutters, H, in revolving, remove the edge of the welt and form grooves and a raised rib or rim, on which rib or rim the fudge-wheel is afterward run to make imitation stitches, and at the same time burnishes said rib or rim on which the stitches are to be made, so that a neat and handsome finish is given to that part of the boot or shoe sole.

The spiders B E can be adjusted relatively to each other to operate upon a. sole of any thickness. After the cutters H II have operated they may be removed and the burnishers K fixed in their places on the spiders B E, when the same manipulation of the boot or shoe and of the device herein described will bnrnish the sole-edge. 'lhese burnishers K have beveled edges and shoulders, but their edges are rounded instead of being sharp and cutting, as are those of the cutters H ll, while in other respects they are the same.

This device is applicable not only to boots and shoes for trimming and polishing the edges of the soles, but can also be applied to the manutacture of wood moldings and the like. The same device can also be applied to shaving and burnishing the heels of boots and shoes, as it can be adjusted to shave and burnish heels of different heights.

It is the general custom, in niakingline and medium shoes, to cutaway the bottom edge, and the practical advantages of so doing are, that it prevents the outer edge from roughing up, gives a neater finish and 'ghter appearance, and prevents the fuzz fro. coming over on the edge while being sandpa \ered.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. A u edge trimmer or burnisher constructed substantially as herein shown and described, consisting of screw-shaft A, provided with collar a, spiders B E, carrying radially-adjustable cutters H H, provided with alternating beveled edges and shoulders, guides O F, and nut G, as set forth.

2. In an edge trimmer or burnishcr, the combination, with the shaft A, provided with a key or spline, g, and collar a, of the outer guide, 0, outer spider, B, and spring D, substantially as herein shown and described, said 60 guide revolving on and with the hub of said spider, as set forth.

3. In an edge trimmer or burnishcr, the combination, with the screw-shaft A and inner spider, E, of the inner guide, F, provided with openings r, substantially as herein shown and described, said guide revolving independently on the hub of said spider, as set forth.

4. In an edge trinnner or burnishcr, the radially-adjuslable cutters H H, provided with alternating beveled edges and shoulders I 1', respectively, substantially as herein shown and described, said edges and shoulders being designed to form the desired ribs and channels on the upper and lower edges of the hunt or shoe sole, as set forth.

5. In an edge trimmer and burnishcr, the spiders B E, provided with slotted arms for the adjustment of the cutters or buruishers, substantially as herein'shown and described. 80
